8.3 Performing care and control work
Dismantling and cleaning of the chuck
After thoroughly cleaning the chuck, slightly grease it on the outside with special
grease (Art.No. 51/1) before re-installation
Tighten the chuck only slightly when re-installing! In normal operation (right-hand
rotation), the chuck tightens itself.
In order to preserve the chuck's accuracy and service life, a tool or the protective
pin provided from factory must always be clamped - even when the unit is not be-
ing operated.
Never clean the handpiece with compressed air!
The corresponding chuck tools can be found on the underside of the handpiece
rack.
